Design and Vibration Analysis of Composite Panels

Composite panels are used largely in aerospace and aviation industries, marine and civil engineering applications because of its properties such as light weight, high strength, high stiffness and good shear properties. Thus it is essential to improve the properties of composite panels. Composite materials may have big advantages over steel in automobile manufacturing. Composites are used to make safer, lighter and more fuel-efficient vehicles. A composite is composition of a high-performance fiber (e.g. carbon or glass) in a matrix material (epoxy polymer) that when combined provides desired properties compared with the individual materials. From vibration point of view composites absorbs more vibrations as compared to metals. Because composites dissipate the energy of vibrations, non-elastic, for making the composite material well suited for applications ranging from equipment mounts to athletic shoe insoles. So in this project we are trying to find out best composition of composite for vibration. For this specimens will be prepared for vibration testing. FFT analyzer used to get dynamic response at particular frequencies & results will be correlate with FEA. FEA of composite panels is done using CATIA V5R20 and ANSYS R15.0
